Abstract: A cable clamp for securing a control cable to a kill or choke line in a mud riser used in offshore drilling of oil and gas wells is described. The cable clamp is comprised of two portions, a fixed portion which remains secured to the kill or choke line and a removable portion which can be engaged to or quickly released from the fixed portion to secure or disengage the control cable. The fixed portion includes a U-clamp, and the removable portion includes cooperating hinged members, each member mounting resilient pad and both members for securing said hinged members together to clamp said cable.

Abstract: A quick connect/disconnect coupling assembly particularly adapted for underwater use, having a pair of coupling members, one of which is mounted on a relatively rigid structure, and a sleeve mounted over the first coupling member for relative axial and rotational movement. The sleeve is guided by a single or double J slot between axially extended locking and axially retracted unlocking positions. In the locking position, a cammed surface on the inside of the sleeve engages a ball and socket arrangement on the coupling members to prevent the coupling members from becoming unlocked; in the axially retracted unlocking position, the cammed surface of the sleeve is moved away from the ball and socket arrangement to permit free radial movement of the ball out of the socket and relative axial movement of the coupling members into and out of coupling engagement with each other. The sleeve is lockable in the axially extended locking position to provide a positive lock.
